Masonary as an item of SectionList

[orhunkupeli]

Hi,

I would like to use masonary as an item of SectionList. However, I need to define listKey={(item, index) => 'A' + index.toString()} to the Column object's Flatlist in order to use it as a child of SectionList. Could you please make a development for it. Because, I don't want to intervene the library in order to get updates.

Thanks
